If you're looking for a decent mainstream smartphone that doesn't break the bank and which will run on Ice Cream Sandwich, then the Sony (Ericsson) Xperia Ray is a possible contender.
The smartphone, which currently runs Android 2.3 Gingerbread, is available for £189.95 at Phones4U, a price that includes £10 Orange airtime and the phone is likely to be unlocked but branded.
The Ray is part of the second generation of Xperia phones which were launched later in 2011.
Like its bigger brother, the Xperia arc, it has a 1GHz single core Qualcomm Snapdragon system on chip, an eight megapixel dual LED camera (with HD recording and Exmor-R technology), plus a 854x480 pixel display (although the one on the Ray is 3.3-inch rather than 4.3-inch) infused with the Reality Display technology.
Sony has also bundled its proprietary Timescape user interface, plus the Mobile Bravia Engine and a number of sensors.
At £190, the Xperia Ray doesn't have much competition. You can get the Xperia Play for slightly less ,but it is much bulkier and its camera is not as good. Neither HTC, Motorola, Samsung or LG have an Android contender within this price range.
